Write list of files with relative path, to file, via batch script

Question

I want to list all files (with relative path) in a folder with a specific sub-folder, and write that list to a text file. The folder is a network folder so I can not set it as current directory. All this via batch script.

So like this:

Folder structure:

\\OtherComputer\MyFiles\libs
--File1.dll
--File2.dll
\\OtherComputer\MyFiles\libs\Editor\
----File3.dll

I want to generate a file with the following text:

File1.dll
File2.dll
Editor\File3.dll

This is how far I have come:

SET LibPath=\\OtherComputer\MyFiles\

break >"%LibPath%metadata"
for %%F in (%LibPath%*.*) do (
  echo %%F>>"%LibPath%metadata"
)
for %%F in (%LibPath%Editor\*.*) do (
  echo Editor\%%F>>"%LibPath%metadata"
)

But this solution write the full path. I tried this to remove the path:

set str=%%F:%LibPath%=%

But it does not seem to handle variable SET or the %%F variable too well inside a for-loop.

Is it even possible? Would like to not have to write a C# executable for this.

Thanks in advance!

Answer 1

Try the following:

@echo off
setlocal enabledelayedexpansion

set "dir=\\OtherComputer\MyFiles\"

FOR /F "tokens=*" %%f IN ('dir /s /b /A-d "%dir%"') do ( 
    set "full=%%f"
    echo !full:*%dir%=!
)

• setlocal enabledelayedexpansion, in addition to creating a localized environment, turns on delayed expansions of variables, which allows variables to be modified inside the for loop's body and used with their modified values. (see help set). Note that in order for a variable to be expanded dynamically, you must enclose it in !, not %; e.g., !full! instead of %full%.

  • Note: A side effect of enabling delayed expansion is that any ! characters are interpreted as part of a variable reference, resulting in potentially unwanted removal of ! chars. from strings, such as in echo hi!. To output a literal ! while delayed expansion is enabled, use ^^! in unquoted strings, and ^! in double-quoted strings. Furthermore, literal ^ chars. in double-quoted strings then have to be represented as ^^.

• dir /s /b /A-d "%dir%" lists all files - and files only, due to excluding directories with /A-d - in the current subtree (/s), as paths only (b). Note that using /s implies that full paths are output.

• set "full=%%f" sets aux. variable full to the absolute path being processed in the current loop iteration.

• !full:*%dir%=! then strips the input dir.'s path from the absolute path using prefix string substitution, leaving the relative path desired (again, see help set).

Just to contrast this with a PowerShell (v3+) solution, which demonstrates how much more advanced PowerShell is compared to cmd.exe.:

$dir = '\\OtherComputer\MyFiles\'
(Get-ChildItem -File -Recurse $dir).FullName.replace($dir, '')

Answer 2

I have a way to to this with two bat files:

code1.bat: Looping through all the files in "C:\Mypath"

@echo off
FOR /F "tokens=*" %%G IN ('dir /s /b C:\Mypath\*.*') do ( 
CALL code2.bat %%G
)

code2.bat: removing the main path string

SET _var=%1
SET _endbit=%_var:*Mypath\=%
Echo %_endbit%

Probably can be done in one file... take a look at http://ss64.com/nt/
